Heterogeneous catalysts obtained by grafting metallocene complexes onto mesoporous silica
THE synthesis of mesoporous siliceous solids with large-diameter channel apertures (25–100 Å) has greatly expanded the capabilities of heterogeneous catalysis1–7. The large apertures in such mesoporous silicas ca...
